AI Technical Summary
Existing warm knitted fabrics cannot effectively conduct heat when worn, resulting in the inability of body heat from hot parts to cold parts, causing body temperature to polarize and prone to illness.
Several through holes are weaved on the intermediate layer, and through holes are set up at the intersection of the convex strips of the two contact layers, so that the grooves between the convex strips of the two contact layers are connected, and the temperature transfer capability of the fabric is improved.
The hot air in the insulation air cavity is transported through the through holes of the intermediate layer, and the through-air cavity is formed by vertically setting the convex strips of the contact layer, which improves the warmth preservation performance of the fabric.

Technical Field
[0001] The utility model relates to the technical field of grey cloth, and more specifically, to an air layer warm-keeping knitted fabric. Background Art
[0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly influence the color and shape of clothing.
[0003] Some existing thermal underwear are made of composite knitted fabrics. In order to ensure the thermal performance of the thermal underwear, the inner layer of the composite knitted fabric is generally woven with natural thermal fibers, such as cotton fibers and wool fibers. However, when the existing thermal knitted fabrics are made into thermal underwear and worn on the body, they cannot conduct heat, resulting in the fabric only keeping warm the hot parts of the body, and failing to conduct the heat emitted by the body to the cold parts of the body, resulting in polarization of body temperature and easy illness.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an air layer thermal knitted fabric, by weaving a plurality of through holes on the middle layer, the through holes are set at the intersection of the convex strips of the two contact layers, so that the grooves between the convex strips of the two contact layers are connected, thereby enabling the overall fabric to have better temperature transfer and increase the thermal insulation performance of the fabric.
[0006] The above technical purpose of the utility model is achieved through the following technical scheme: an air layer warm knitted fabric, including an intermediate layer and two contact layers respectively arranged on both sides of the intermediate layer, the intermediate layer is woven by combs GB1 and combs GB2 to form a plurality of through holes, and the two contact layers are woven by combs GB3 and combs GB4 to form a plurality of convex strips.
[0007] Preferably, the convex strips of the two contact layers are arranged perpendicular to each other, and the through hole is established at the intersection of the convex strips of the two contact layers.
[0008] Preferably, the organizational structure of the comb bar GB1 is 2-3 / 3-4 / 3-2 / 4-5 / 4-3 / 4-5 / / 1 through and 1 empty; the organizational structure of the comb bar GB2 is 4-5 / 4-3 / 4-5 / 2-3 / 3-4 / 3-2 / / 1 through and 1 empty.
[0009] Preferably, the yarn inlay movement of the comb bar GB3 is: (1-0 / 1-2)X3 / (1-0 / 3-4)X3 / / full threading; the yarn inlay movement of the comb bar GB4 is: 1-2 / 1-0 / / full threading.
[0010] Preferably, the middle layer is formed by weaving a composite yarn, and the composite yarn is formed by twisting a plurality of acrylic fibers and a plurality of cotton fibers.
[0011] Preferably, the contact layer is formed by weaving a second composite yarn, and the second composite yarn is formed by twisting a plurality of acrylic fibers and a plurality of wool fibers.
[0012] The utility model has the following beneficial effects:
[0013] When the fabric is made into clothing and worn, the heat emitted by the body is directly retained in the thermal insulation air cavity formed by the convex strips of the contact layer and the middle layer, and the hot air in the thermal insulation air cavity is transported through the through holes on the middle layer. Since the convex strips on the two contact layers are arranged perpendicular to each other, the air cavity can pass through the entire fabric, so that the fabric can have a better temperature transfer effect and increase the thermal insulation performance of the fabric.

[0022] Middle layer 1: Put a plurality of acrylic fibers 6 and a plurality of cotton fibers 7 into a twisting machine for twisting to form a composite yarn 5, put the prepared composite yarn 5 into a large circular knitting machine and weave it through a combing bar GB1 and a combing bar GB2 to form a middle layer 1, the structure of the combing bar GB1 is 2-3 / 3-4 / 3-2 / 4-5 / 4-3 / 4-5 / / 1 through 1 empty; the structure of the combing bar GB2 is 4-5 / 4-3 / 4-5 / 2-3 / 3-4 / 3-2 / / 1 through 1 empty, and the middle layer 1 with an array of through holes 3 is woven through the combing bars GB1 and the combing bars GB2.
[0023] Contact layer 2: a plurality of acrylic fibers 6 and a plurality of wool fibers 9 are placed in a twisting machine for twisting to form a composite yarn 2 8, and the composite yarn 2 8 is placed in a large circular knitting machine and woven through a combing bar GB3 and a combing bar GB4 to form a contact layer 2, wherein the yarn padding movement of the combing bar GB3 is: (1-0 / 1-2)X3 / (1-0 / 3-4)X3 / / full penetration; the yarn padding movement of the combing bar GB4 is: 1-2 / 1-0 / / full penetration, and a plurality of convex strips 4 are formed on the contact layer 2 through the weaving techniques of the combing bars GB3 and GB4.
[0024] The contact layer 2 is cut into two pieces of cloth, and the convex strips 4 on the two pieces of cloth are vertically set and sewn to the two sides of the middle layer 1. At the same time, the through holes 3 on the middle layer 1 are connected to the intersection of the convex strips 4 of the two pieces of cloth to finally form an air layer warm knitted fabric.
[0025] Acrylic fiber 6 has the characteristics of softness, warmth retention and good strength; cotton fiber 7 has the characteristics of softness, moisture absorption, breathability and wear resistance; wool fiber 9 is elastic, resilient, warm and moisture-absorbing; the through hole 3 of the middle layer 1 can make the cavity between the convex strips 4 of the two contact layers 2 connected, so that a connected air insulation layer covering the entire fabric is formed in the fabric.
